Hi,

Yes, I'm aware of this and this is what I checked first. In fact, I 
removed the initrd from the directory where vmlinuz was located and it 
produced an error during PXE boot. Thus I am confident that I am using 
the intended vmlinuz and initrd. What really worries me is that the end 
result, just after the %pre script (the pb is the same is the script is 
empty), is that /lib/modules contains modules for an older kernel 
version... The only possibility for me would be to have the old initrd 
version (7.0) but I don't even have it on my system!

Cheers,

Michel
